the braces 4 which support the bearings 5 having rotatably mounted therein the hollow shaft or sleeve 6 which extends the width of the bodyof the car, said sleeve having an enlarged central portion? having a slot 8 in the lower or under side thereof. On the ends of the sleeve arethe heads to which are secured the brackets 9, while connecting the brackets is a brace bar 10.

J ournaled in the sleeve 6 is a shaft 7 having a sprocket wheel 11 located in the enlarged portion 7 of the sleeve, while mounted on each end of the shaft is a beveled gear wheel 12, said gear being in mesh with the beveled gear wheel 13 of the tubular shaft 14 and thegear 15 of the solid shaft 16, the shaft 14 passing throu h an gpening in the end of the bar 10.an held Y while the shaft 16 is journaled in the tubular shaft 14 and has its lower -end supported by the bracket 9. correct position, I mount upon each shaft 16 the loose sleeve/18 held in positionv upon the shaft by the collars 19, said sleeves being connected by the brace rod 20 which serves in connection with the shafts and bar 10 to form a strong rectangular frame.

It will be observedthat I have mounted upon the upper end of each of the shafts the blades or vanes 21, while leading from the sprocket wheel 11 to a power supplying-device 22 is the chain 23 which serves to revolve the shaft 7 which shaft through the medium of the beveled gears causes the tubular shaft and solid shaft journaled therein to revolve in opposite directions and thus create through the blades a strong lifting force for operating the flying machine, as will be readily understood by reference to the drawings.

To all whom it may concern:

Be it known that I, DAVID A. FLANIGAN, a citiz'enof the United States, residing at Springville, in the county of Utah and State of Utah, have invented certain new and useful Improvements in Airships, of which the following is a specification.

My invention relates to improvements in mechanical movements, and the leading object of my invention is the provision of im proved mechanism for the transmission of power which shall be particularly adapted for use in driving flying machines of the helicopter type.

A further object of my invention is the revision of ine of this character a mach which shall be adapted either for use in elevating weights as a helicopter of for the production of power'through the medium of air or other fluid currents impacting against the vanes or blades carried by the shafts.

Another object of the invention is the provision of strong, simple and durable mechanism of a light but efficient type which may be interchangeably employed for use in lift ing a flying machine and sustaining the same or for a power motor.

To attain the desired objects, my invention comprises mechanism for attaining certain mechanical movements, said mechanism comprising a'tubula: shaft having asecon shaft j'ournaled therein, each of said shafts being provided with vanes or blades, and a shaft connected by gearing to the other end of said pair. of shafts in such manner that the tube and shaft journaled therein revolve in opposite directions while the other shaft revolvesin a constant direction and serve either to drive the pair of shafts or be driven thereby, the invention further residing in the novel features of construction and combination and arrangement of parts for service substantially as described and as illustrated in the accompanying drawings.

Figure 1 represents a side elevation of complete machine. Fig. 2 represents a front view thereof. Fig. 3 re resents a sectional View of the hearings or the shafts, the tubular shaft being shown in section, and, Fig. 4 represents a detailed view of-the shaft adjusting mechanism.

In the drawings, the numeral 1 designates the body of the car havin located at the rear the rudder 2 operated the handle 3, and rising from the body f. t e machine are To aid in con scent of my air ship when equipped with the above described lifting fans, sleeve 6 the rock arm 2 1 having pivotally secured to its outer at its other end to the lever 26 pivoted to the bracket 27 carried by the base of the body, said bracket being a segment 28 adapted to be engaged by a dog 29 carried by the lever to lock the same in adjusted position. In operation, the adjustmen-t of the lever 26 serves to swing the sleeve 6. and thus the brackets and shafts at an angle to the car, the direction in which end the link 25 pivoted a collar 17 bearing against the said bar,

In power transmission mechanism, the et, rudder and supports, of a shaft mounted therein, and its outer ends metrically opposite points, respectively, upon tubular shafts having journaled therein solid shafts, the said'pairs of shafts being adapted to be either revolved "in opposite dimain shaft in a' constant direction, said pairs of shafts same in adjusted position. n
